What are the precautions for utilizing thermal camera in the new colon virus infection measures?

　One of the corporate business continuity plans (BCP) is to prevent the expansion of infectious diseases in the company.From the beginning of 2020, a new colon virus infection that rampages around the world has made it a key challenge to work on the BCP.We interviewed Konica Minolta Japan (Minato -ku, Tokyo), which proposes to prevent the spread of infectious diseases through a network camera.

Notification in the red frame when detection (thermal + visible image)

-It seems that thermal cameras are increasing as a measure to prevent the new colon virus infection.

　"In February, inquiries have begun to increase. In March, we have been busy responding every day. Inquiries from the General Affairs Department, people who are close to management, and departments involved in safety.There are many "

-Suramal camera was a problem before, and even in severe acute respiratory syndrome (SARS), it was sometimes found in each media.Does it mean that it is effective in preventing infectious diseases?

　"I think the point is to use it after understanding what kind of position for infectious diseases is used. First of all, it is not possible to determine if you are a virus infected with a thermal camera.The same is true, the purpose of using a thermal camera is "detection of people with fever".

-The idea is to restrict the admission as a person who may have infected as a symptom and prevent infection in a specific area.In other words, is the role of the thermal camera perceived as "easily measuring body temperature and efficiently identifies the fever?"

　"This is the case, but what is easily misunderstood here is that a thermal camera is a device that measures the surface temperature, so what is the temperature of the contact type thermometer generally considered to be body temperature.It's different. "

-Isn't it body temperature?

　"Yes. Measure with a thermal camera is the surface temperature of the skin. In the first place, the temperature of the human body varies depending on the location, and the surface temperature of the limbs and face is susceptible to the season and environment. For example, cold outside.Immediately after hitting the outside air, the surface temperature comes out low, and the surface temperature is high immediately after exercising, such as running. On the other hand, body temperature inside the body keeps the internal organs.Therefore, it is originally stable. Therefore, in order to simply measure the one that is close to the internal temperature of the body, it is measured in places such as armpits and mouth (tongue) with a contact type thermometer. "

-The fingertips in winter, when the temperature is low, is cold.The difference from the thermometer that I usually use casually is a study again.But the fact that a thermal camera measure the temperature of the skin does not mean that the body temperature is not known, that is, the heating person is not known?

　"I do not know the body temperature itself, but the higher the body temperature, the higher the surface temperature, so it is a simple screening that is considered as" a person with a high surface temperature of the skin = a person who may have a fever ".It can be used. "

-Is that the thermal camera is detecting a possibility person.

　"Yes. For those who have detected high temperature with a thermal camera, there may be situations where it is necessary to use a contact type thermometer separately to measure the accurate body temperature."

発熱者検知での注意点

-Please tell us if you have any precautions when using a thermal camera like this as an infection prevention measure.

　"There are two major things. The first is that you can see the skin of the target person. If you wear masks, hats, glasses, and sunglasses, you will measure the surface temperature of those clothing.Then, it is desirable to remove the hat etc. and make it easier to measure by putting out "forehead" etc. "

　"The second is a constant measurement environment. In principle, the measurement value changes when the" distance "or" angle "between the measuring material and the thermal camera is different. If the measurement location is different, these distance and angle are different.In addition, the measurement values are not constant because the temperature environment such as outside temperature and room temperature changes. Therefore, it is important to set the measurement environment, such as fixed the measurement location as much as possible, so that the target person can measure at a certain distance.Is. In an environment where the temperature changes drastically, regular equipment adjustment is required. "

M16 Thermal

-Could you tell me if you have any characteristics about the thermal camera products you handle at your company?

　"The thermal camera we handle is a thermal camera made by MOBOTIX (Mobotics). Mobotix products have high robustness for customers."

-What are the functional features?

　"If you give three popular functions," 2 eyes (cancer) "," Notification ", and" Recording "."

-What is "2 eyes"?

　"It will be a model with two lenses on one body. It is called" two -lens camera "because there are two lenses that are the eyes of people. There are many inquiries about viral infection.M16 Thermal "can also shoot color images in addition to thermal camera images. Therefore, it helps to distinguish who the fever is a fever."

-Certainly, I don't know who is just a thermal video.How about "Notification"?

　"Because our thermal camera is not a handy type, it is basically used in fixed installation. The operator watching the monitor video is usually called to the high temperature, but the camera is the flow.If you detect the specified temperature or higher, you can not only notify the computer screen for the operator, but also notify people in other places through the network. "

-Are you notified, for example, other personal computers connected by network?

　"You can receive notifications not only for personal computers, but also on smartphones and tablets where the network is connected."

-Is that it means that some cases will be able to respond to people who are not at the site depending on the case?

　"Yes. In the case of urgent, it is desirable to respond nearby, but depending on the time and the place to detect, there is a possibility that you can check the notification and respond at a remote place."

-There is a very practical function in the field of labor shortage.So what is the last "recording"?

　"Originally, Mobotix, a network camera, has a recording function, and can be stored with internal SD cards in a few days."

-How is it useful in operation?

　"If there are many people, it may be difficult to confirm the person and the situation. In that case, you can check the target person by looking at the video just before the recorded. In addition, you can index only the timing of detected.You can search and play quickly because you can do it. Also, in some cases, when considering daily operation improvements, it is possible to check the actual compatible video, which can lead to improvements in accordance with the facts."

―We will return to the first question, can you summarize whether it is effective in preventing infection?

　"As I mentioned so far, unfortunately, 100%of the thermal camera cannot be detected or prevented, but it is difficult to prevent 100%infection in other ways, such as masks and hand washing."

　"Basically, we believe that preventing these means to prevent it is a realistic infection measure. Hand washing and wearing masks can be taken by individuals, but identification of infected people and invading specific areas.I think that the act of preventing is a measure that can only be taken by an organization, such as companies and facility managers. In that sense, organizational officials with a sense of crisis use thermal cameras as one of the organizational measures.It seems that you are considering it. "

　"In addition, it can be used for annual influenza measures regardless of the new virus, and it is not a consumable, so it can be used for a long time once purchased, and it is very efficient if many people come in and out.I guess
